CVE-2018-14612 (retired)

Priority
Description
An issue was discovered in the Linux kernel through 4.17.10. There is an
invalid pointer dereference in btrfs_root_node() when mounting a crafted
btrfs image, because of a lack of chunk block group mapping validation in
btrfs_read_block_groups in fs/btrfs/extent-tree.c, and a lack of empty-tree
checks in check_leaf in fs/btrfs/tree-checker.c.
Ubuntu-Description
Wen Xu and Po-Ning Tseng discovered that btrfs file system implementation
in the Linux kernel did not properly validate metadata. An attacker could
use this to construct a malicious btrfs image that, when mounted, could
cause a denial of service (system crash).
